“…However, the final acidity index (M = 0.12%) was lower than the values established by ANP/2014,(ANP 2014). After 12 months of storage, the values are below the values found by Melo and Souza for biodiesel from seed oil and pulp, respectively (Serqueira, et al 2015, Souza, et al 2016. Acidity is an essential factor in the quality control of biodiesel because the presence of free fatty acids, triggers an entire oxidative process of the fuel, causing deterioration of parts, corrosion, incrustations and deposit of waste (Portela, 2011).The hydrolytic or oxidative rancification, the main oxidation mechanism of oils and fats, is associated with the reaction of water or air oxygen with fatty acids, especially unsaturated fatty acids (Bobbio & Bobbio 1992).…”

The influence of storage conditions on the properties of biodiesel from macaúba (Acrocomia aculeata (Jacq.) Lodd. ex Mart). seed oil was evaluated. The biodiesel samples were stored for 12 months at 25 °C and 4 °C. The physical properties of the biodiesel: acidity index, peroxide and refractive index, flash point, and oxidative stability were determined. The chemical composition of the biodiesel was determined by gas chromatography coupled to mass spectrometry and by infrared spectroscopy. The analysis of the main components and the Hierarchical Analysis were used to group the samples. The oxidative stability of biodiesel, which developed low acid and peroxide indexes, and the ester composition were maintained stable, regardless of the storage method. However, storage at 4 °C proved to be more efficient in maintaining the characteristics of the biodiesel. The high quality of biodiesel and its stability confirm the potential of the agro-industrial use of biodiesel from Acrocomia aculeata.

“…Due to the low oxidative stability, it is necessary to use antioxidant additives to improve such property. On the other hand, although it is not in accordance with the specification, the oxidative stability of the synthesized biodiesel is still higher than biodiesels from other sources such as soybean, karanja (Pongamia pinnata), jatropha (Jatropha curcas L.) and other cottonseed biodiesels reported in the literature (Dwivedi and Sharma, 2016;Rawat et al, 2015;Roveda et al, 2016;Serqueira et al, 2015;Serqueira et al, 2014).…”

The objective of this study was to evaluate the antioxidant activity of the natural extracts catechin, curcumin and quercetin on the oxidative stability of methylic cottonseed oil biodiesel. The oxidative stability was evaluated using the Rancimat method (EN 14112) for biodiesel with 500, 1000, 1500, 2000 and 3000 ppm of additives, and compared with the commercial antioxidant butyl hydroxyanisole at the same concentrations. Kinematic viscosity was also evaluated at the same concentration. All additives had a positive effect on the oxidative stability; moreover, all extracts presented better results than BHA. Catechin was the most effective additive, achieving an induction period almost three times greater than BHA for 3000 ppm. In addition, all three extracts caused a reduction in kinematic viscosity, but it remained within the technical specification. These results prove catechin, curcumin and quercetin to be powerful natural antioxidants.

“…Figure 1. Induction Period of samples in functionof storage timeSerqueira et al (2015) also observed an increase in the IP of biodiesel from cotton oil with the addition of 1000 mg kg -1 of curcumin. This increase in the IP is assigned to the ability of curcumin to kidnap free radicals, inhibiting lipid peroxidation(Sun et al, 2002;Marchi et al, 2016).It should be emphasized that the 180 days in the oven at 43 ºC correspond to approximately 2 years stored at room temperature.…”

Biodiesel has emerged as an alternative source to fossil fuels. In Brazil, to assign a good quality to biodiesel, regarding oxidation stability, it is necessary that the biodiesel shows a minimum of 8 h of induction period (IP), determined at a temperature of 110 ºC by the Rancimat method, in accordance with Resolution No. 45/2014 of ANP. As, in most cases, the biodiesel produced does not meet the established standards of oxidation stability, it is necessary to add antioxidants, which slow down the oxidative process. Thus, this paper proposes a study on the action of curcumin, a natural antioxidant, on commercial biodiesel produced from blending 80% soybean oil and 20% beef tallow. In this study, samples were stored for 180 days at 43 ºC, according to ASTM D4625 recommendations. It was possible to observe that curcumin ensured greater oxidation stability to biodiesel and lower acid number values during the period of storage. Kinetic studies showed that samples with the addition of curcumin showed the highest value of activation energy for the oxidative degradation process, demonstrating that adding this natural antioxidant makes biodiesel more resistant to oxidation.
